IMPROVE!) MACHINE FOR WIRING- RING-IES.

The Schedule referred to in these Letters Patent: and making pari: ofthe name.l

To all whom it may concern Be it known that I, ELLIS LUTHER, of WestTroy,

in the county of Albany, and State of New York, have invented anImproved and that. the following is a full, true, and exact descriptionthereof, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure 1 is a perspective viewof a machine coutaining my said invention;

Figure 2 is a view of the same, from above; i

Figure 3 is a section of my saidmachine, showing the manner in which thehinge is held duringthe process of wiring; n p

Figure 4 is another section of my said machine,exhibiting the mode ofconveying Ythe 'wires from the hopper to the groove, ii'om which theyare forced into the jointslof the hinges;

Figure 5 is a section of my said machine, through the groove abovementioned;

Figure 6 exhibits the construction of the revolving cylinder,hereinafter described;

Figure 7 shows one of the wires; and

Figure 8, the separate parts of a hinge.

Figure 9 represents the shaft and plunger, bywhich .the wire is forcedthrough the joints of the hinge and Figure 10, the manner in which theplunger maybe supported vby sliding blocks, as hereinafter described.

Having stated the natureof my said invention, I

will proceed to describe the construction and operation thereof'.

A is a strong frame of wood or ports the shafts B and C.

As shown in the drawing, the shaft B .is actuated by a crank, but it ismy intention to have it driven by steam or other power.

`Motion is communicated from shaft B to shaft (i, by means of a bevelledgear, as shown in iig. 2.-

At the end ofthe shaft yB is attached, in the usual manner, thereciprocating shaft I), to which is attached the plunger I.

The said reciprocating shaft, 'below' the joint, at X, slides in aframe, Y Y

K is the stationary and L the movable jaw of a vise, which opens farenough to receive the joint of a hinge.

At the place where the hinge is inserted and held the jaws areconstructed with plates of steel or other `suitable metal at their uppersurface, which plates project toward each other, slightly beyond-thebody of the jaws.

metal, which sup- The said jaws, under the hopper or Ireservoir, each`contain a small semieircular groove, half the size of the wire tobeused, so that when the vise is closed, the two grooves will'form acircular passage the size ofthe wire aforesaid. This groove is upon anexact Machine for iViring Hinges;

line with the joint of the hinge, when placed Vin the y.

l vise, and with the plunger I.

J is a platform under that portion of the ymovable jaw in, which thegroove is constructed, and its top is just even with the bottoms of thegrooves, so that ifr a wire is dropped on the platform between the jaws,

it will, when the jaws-are shut, be enclosed in the circular passageformed by said grooves,fas aforesaid.

The shaft CY carries the cams S S, which, at 'each revolution, close thevsie by forcing the movable jaw L against the stationary jaw K.

After therv cams have ceased to act upon the said movable jaw, itisdrawn back to its former positionby the weight l and cord h, whichpasses over the pulley t.

j M is a species of hopper, whose width is but a trie greater than thelength of the wires to`be used.

The bottom of this hopper slopes from each end' to' an oblong aperture,near the centre, to which is closelyj tted the surface ot' the revolvingcylinder O, as shown', l

in iig. 4.

In the surface of this cylinder is constructed the longitudinal channelor recess a, of just snicient size to hold a single wire.- y

The cylinder revolves in a kind ofdrum, N, which contains, at thebottom, an aperture, c.

P is a plate of metal, fixed upon the movable jaw under the hopper, andhaving the oblong yrecess i;of sutlicient dimensions toadmit a singlewire.

lhe cylinder 0 is revolved by means ofja band passf ing over the wheelsR It.

V is a projection on one ofthe cams, which, at each revolution, strikes.the arm 1^ .of the compound level' W and depresses it, 'therebyelevating the arm p of said lever, for the purpose hereinaftermentioned.

c is a spiral or other spring, which brings the said lever' back to itsformer position after it has been actuated by the-cam and projection V,as aforesaid.

i] g are small blocks, made to slide in the frame Y Y, for the purposeof supporting the plunger I, and are attached by the chain n n to eachother and to the shaft. They may be employed in any number desira. vble, which will not interfere with the necessary length l of stroke. f f

The mode 'of operation of fmy said invention is as follows:

The hopper M is first filled with wires, piled across the hopper andparallel with the cylinder O.

The shaft B is then put in motion, causing the shaft C and the cylinderO to revolve.

As the cylinder O revolves, bringing the recessv u under the opening inthe bottom of the hopper, one of the wires will drop into the recess cand will be carried round with the cylinder until it reaches theaperture c, in the Vdrum N.

At this moment the movable jaw L iS forced toward the stationary jaw K,by the operation of the cams S S, and the recess f, in the plate P, isbrought directly under the said opening c, aud the wire drops into thesaid recess f from the-cylinder O. Y

The wire is retained in said recess f until, by the continued revolutionof the shaft G, the cams S S release the movable jaw L, which isimmediately drawn back by the cord and weight T, allowing the wire todrop on the platform J.

At this moment a hingeisplaced in thevise in such a manner that thejoint of the hinge is between the jaws and so that edges of the metallicplates L K will grasp the upper surfaces ofthe joint on each side closeto the leaves ofthe hinge, thus holding the hinge firmly by the joint,and preventing-the slightest motion.

As the jaws are thus closed, the wirc upon the platform J is enclosed inthe double groove or cylindrical passage ll, the plunger I beingsuiiiciently drawn back to permit its entry into said passage.

Byvthe further revolution of the shaft B, the reciprocating shaft D isthrust forward, and the plungerA I, moving in the double groove orpassage d, forces the wire into the joint of the hinge with perfectaccuracy.

As soon as the insertion of the wire is complete, the cams S Sagainrelease the movable jaw L, and, as the vise opens, the projection Vstrikes the arm l of the compound lever W, depressing it and elevatingthe other arm, 11, so that the hinge is thrown out of the vise and fallsinto a receptacle provided for that purpose. Another hinge is thenimmediately fixed iu the vise ready to receive the next wire, which, bythis time, is dropped on the platform J. Y

i By this means a wire is inserted at every revolution of the shaft B,and much more rapidly and accurately than can possibly be done Aby hand,and dispensing Y with a very large amount of manual labor.

As the plunger I cannot be larger than the wire to be inserted, it isobliged to overcome a great deal of y sage above mentioned, theseblocks-will be forced to gether, but, when it is drawn back, they willbe distributed along its length by means of the chain 71, and willeifectually counteract any deviation of the plunger from a right line.

What I claim as new, and desire to secure by Letters Patent, is 1 l. Thecombination and arrangement together, in the manner described, ofthejaws K L, dischargingfollower e, and the mechanism by which the movablejaw L is advanced and retracted.

2. The combination of holding-jaws K L, with block J, slatted side P,recessed rotating cylinder O, hopper M, and reciprocating plunger I, allconstructed and arranged as set forth.

` 3.v The receiving-plate J and movable jaw L, in combination with theslatted side P, the recessed rotting blank-feeder O, and hopper M, allconstructed and arranged as specified. v

4. The construction and arrangement, with thereciprocating plunger I, ofmovable'rest-blocks g, andl chains n, as and for the purpose specified.

In witness whereof, I have hereunto set my hand, this 2d day ofFebruary, 1869.

ELLIS LUTHER.
